Charles Alcock is managing editor of the AIN Media Group, having rejoined the company in 2019. He has been an aviation journalist since 1986, and previously worked for AIN from 1990 to 2017, most recently as editor-in-chief. His main focus is on covering new aviation technology and business models, as well as international news.
Having been raised in the London area, Alcock studied at the University of Manchester in the UK and earned an honors degree in Politics and Modern History. He speaks English and French, and some German.

Autonomous aircraft are critical to the success of urban air mobility (UAM), according to&nbsp;NASA administrator Jim Bridenstine who shared the agency’s vision for the emerging sector&nbsp;during the EAA Spirit of Aviation virtual event in late July. “You can actually make the argument that in the future it's going to be safer to fly an uncrewed aircraft than crewed aircraft,” he said while outlining NASA’s programs to support what the agency now refers to as advanced air mobility to avoid the impression that the new generation of eVTOL aircraft will only have roles in urban areas.
Bridenstine, a former congressman and U.S. Navy F-18 pilot, pointed out that sophisticated detect-and-avoid technologies, including 360-degree sensors aboard future autonomously&nbsp;piloted aircraft, will provide “better capabilities than what a human has” when it comes to avoiding midair or terrain collisions. “I know it sounds crazy, but it is absolutely true,” he said.&nbsp;
According to the head of NASA, the current air traffic control infrastructure “is not going to be able to manage” UAM as currently envisioned with “thousands of unmanned aerial systems operating [at] 400 feet and below and each of those...systems doing dozens of missions in a given day." In his view, this&nbsp;congested airspace will depend on the development of an autonomous system for flight operations.&nbsp; "We need to develop the autonomous system&nbsp;that factors in air space, traffic corridors, route planning, interaction with manned aircraft, terrain avoidance, wind and weather, and the ability not only for the aircraft to be capable of dynamic rerouting, but also use of dynamic airspace, where the boundaries change to accommodate traffic," he said.&nbsp;&nbsp;
For NASA, its continuing investment in and advancing of&nbsp;&nbsp;“leap-ahead” technologies such as UAM,&nbsp;more fuel-efficient propulsion, advanced aerodynamics, and low-boom supersonic research are viewed as essential components for U.S. aeronautical leadership. Many in the industry have acknowledged that the country lost out to rivals like China in the rapidly-growing market for small drones and have argued that this missed opportunity must not be repeated in the eVTOL aircraft sector.
Bridenstine committed the agency to supporting the development of alternative propulsion, including all-electric aircraft, smaller-core jet engines with larger turbofans, and hybrid-electric turbofans, as well as aerodynamic advances such as trussed high-aspect-ratio wings. He maintained&nbsp;that NASA is well-grounded in “doing a lot of the technology incubator work in advance of anybody bringing something to market.”&nbsp;
By way of example, he said the X-59 low-boom demonstrator, developed in cooperation with Lockheed Martin, is intended to prove the efficacy of supersonic flight over land with “such a little boom that it doesn’t disrupt anybody on Earth.” Such a demonstration is seen as critical before Congress would repeal the current civil aircraft overland supersonic prohibition, a move seen as central to more widespread aircraft OEM investment in supersonic.&nbsp;
The administrator said NASA selects its research projects based on “where the market is going,” in cooperation with the FAA and private industry, and added this approach has drawn bipartisan congressional support. “We’re seeing our budget actually increase,” he said. “Our budget is only effective if we can find the right industry partner and then work with them to accomplish these generational, leap-ahead capabilities. We don't go out and just spend our own money on our own projects.”
